Best Practices for Tech Facilitators?

In his blog, the Thinking Stick, Jeff Utecht discusses his ideas for how to secure a position as a tech facilitator. Some discussion ensued about whether or not pedagogy should be a personal decision: should facilitators follow their own beliefs, or should they formulate opinions based on external, formal research, or should there be an oversight organization (such as ISTE) who articulate best practices and determine job descriptions for facilitators? I'm curious what others think about this.
